  • Patent number: 11717274
    Abstract: A syringe is coupled to a biopsy needle through a coupling structure that includes a motor-driven element such as a gear to rotate the needle. The motor can oscillate back and forth to cause the needle to oscillate. Structures are described to permit one-handed operation of the device and automatic motor activation based on attaining a desired plunger position.

  • Publication number: 20220096065
    Abstract: A syringe is coupled to a biopsy needle through a coupling structure that includes a motor-driven element such as a gear to rotate the needle. The motor can oscillate back and forth to cause the needle to oscillate. Structures are described to permit one-handed operation of the device and automatic motor activation based on attaining a desired plunger position. Non-electric motors are described along with a mechanism for axial oscillation of the needle.

  • Publication number: 20220087661
    Abstract: A syringe is coupled to a biopsy needle through a coupling structure that includes a motor-driven element such as a gear to rotate the needle. The needle can have a sharp beveled tip which, in cooperation with rotation of the needle, harvests tissue in vivo via rotation rather than multiple “sticks” into the patient.

  • Publication number: 20190307436
    Abstract: A syringe is coupled to a biopsy needle through a coupling structure that includes a motor-driven element such as a gear to rotate the needle. The needle can have a sharp beveled tip which, in cooperation with rotation of the needle, efficiently harvests tissue in vivo to reduce the need for multiple “sticks” and concomitant patient discomfort and increased time and cost.

  • Publication number: 20040175329
    Abstract: There is disclosed a method for visualizing a body lumen. The method of the invention uses contrast material that preferably adheres to the interior wall of a target body lumen for a period of time sufficient to permit real-time visualization of the lumen and to enable the performance of image-guided diagnostic and therapeutic procedures. Lumens from the cardio-vascular, pulmonary, digestive, reproductive, excretory and central nervous systems may conveniently be visualized. Radiography, nuclear medicine, ultrasound and MRI visualizing systems may be used. Contrast materials for use in the invention are non-toxic, especially non-toxic to the kidney, do not produce allergic reactions, do not stimulate atherogenesis, and preferably comprise iodine or a metal.
